In other words, early 5G chips are able to blast huge amounts of data (say, one large file) with much greater power efficiency than typical 4G, but suffer when they’re forced to dribble data (say, typical web pages with tons of small files) out at 4G-like speeds. Since early 5G devices can simultaneously connect to 4G and 5G networks, software optimizations should enable them to make better choices about where to transmit their data.
